Description: problems when Restore Backup in RHEL4
Details:

I made a pg_dumpall in a postgresql server without problems (using Red Hat
9. and postgresql 8.0.3), but when i attempt to restore this backup in a
RHEL4 (kernel 2.6.9-5 64 bits )i receive a lot of erros: invalid command
\n!

I try to use Fedora Core 4 and i restore the the backup perfectly.

I used:
# pg_dumpall -U postgres > mybackup
# pqsl -U postgres template1 < mybackup

I think that im doing all the procedures right.

Could you help me!
